Kodak says Kodak T-Max RS may be used for more than one film. It can also be replenished.
The maker doesn’t publish a rule for lengthening the time, so the calculator makes no correction.
Capacity, as the maker states it: Tank: 16 8x10-inch sheets per gallon (4 per litre); the capacity can be increased by replenishment (45 mL per 135-36 or 120 roll).
Mixed solution used as a working-tank solution or a replenisher. ... Add 1 1/2 fluid ounces (45 mL) of solution for each 135-36 or 120 roll or 8 x 10-inch sheet (or equivalent) processed. Stir or recirculate the solution thoroughly after each addition of replenisher solution. ... Note: Do not use KODAK T-MAX RS Developer and Replenisher to replenish KODAK T-MAX Developer.
